IMPROVEMENT IN RAILROAO JOURNAL-Boxes.-

Specification forming part of Letters Patent No. 40,@ l0. dated Deccmter8, 15.463.

cause the said roller to deposita uniforml supply of oil on the journalwithout the aid of springs; secondly,in apartition so arranged. withinthe box as to prevent an undue waste of oil; thirdly, in an annular angeor its" equivalent attached to or forming apart of the car Wheel or axlefor restoring superiiuous oil to the-oil-chamber'of thebox; and,fourthly, in an annular flange attached to or forming part of the carwheel or axle for 'preventing" sand, dust, &c., from gaining access tothe interior of .the box.

A' In order to enable others to make and use ourinvention,we will nowproceed to describe its construction and operation.

On reference to the accompanying'drawings, which form a part of thisspecification, Figure 1 is a vertical section of a journal-box, journal,and part of a car-wheel constructed according to our` improvements; Fig.2, a transverse sectionon the line 1 2, Fig. 1; and Fig.

3,asectional plan of the journal-box on the line 3 4. Fig. 2. A

Similar letters refer to similar parts throughout the several views.

A represents the journal of the axle, which is provided with the usualcollar, a, and shoulder b, between which Vts the brass bearing B, thelatter being separated from the top of the box by the key C. l

' D is the exterior casing ofthe box, and is of a form similar or nearlysimilar to journalboxes of the ordinary construction, there being infront the usual detachable door, d, to close the opening, through whichthe brass bearing B, key (l, and other parts described hereinafter areintroduced into the interior. VAt the rear of the box, and concentricwith the axle A', is an annular flange or projection, E,which may beof'different forms, but which we prefer to make beveled on the insidefrom the outer edgedownward toward'the interior of the box, as bestobserved on reference to Fig. l.

F represents a portion of the car-wheel secured to the enlarged portione of the axle A, and on the hub of the wheel are two annulaitlanges, Gand H, the inner ange, G, projecting into the space between the flange Eand the axle, and the outer flange, H, overhanging the said flange E,with which, however, both the anges G and H are free from contact.

The flange G may be of different forms, but we prefer to make it of thepeculiar form illustrated in Fig. l of the drawings-namely, beveled ontheinside f,as well as on the exterior g.

A partition, t, divides the interior of the box into an uppercompartment and. lower compartment, L, the latter of which we term theoil.cha1nber, and in this partition is an opening for the reception of aportion of the frame Jin recesses, in which turn the journals of theroller K, the periphery of the latter running in the oil contained inthe chamber L.

The frameJ has at one end two projections, z' e', which rest onthepartition I, and at the opposite end a projection, j, against the underside of which be'ars the short armv of the lever M. (Shown by dottedlines in Fig. 2.) The fulcrum of this lever consists of a projection, m,bearing on the top of the partition I, and the long arm of the lever ismade so heavy' thatit tends to raise the short arm, and with it one endofthe frame, thereby maintaining the periphery of the oiling-roller K inconstant contact with the journal of the axle.

It will be observed that there are no pins, screws, Or other fasteningsfor maintaining the lever M, frame J, and oiling-roller K in theirproper positions, the lever M occupying a chamber between the front o fthe box and a rib, n, formed within the same, and the frame being connedin its proper position by the said rib n and another rib, q, and by theopening in the partition I within which the frame ts,while the journalsof the roller K have n'o tendency to escape from the recesses of theframe.

be described as follows:

First. Rollers havebeen heretofore used in i journal-boxes for conveyingoil to the journals, but have been maintained in contact with the latterby means of springs, which not only become clogged with the lubricatingmaterial, and more or less deteriorated and inefficient, but aredifficult of application. In 'our improvements the oiling-roller ismaintained in constant contact with the journal by the long Weightedarrn of the lever M acting on the rocking frame J both the latter-thelever and the roller-being simply deposited in the box without thenecessity of any elaborate litting or adjustment, and always remainingin a condition to perform their duties.

Secondly. The partition I tends to maintain the oil within the chamberL, and to prevent that agitation of the oilwhich results in great Wasteof that lubricating material.

Thirdly. Whatever superliuous oil may be conveyed to the bearing by theoiling-roller and vadheres to the axle will, on reaching the point wherethe annular beveled flange G meets the axle, follow the inclinedinterior f of the flange, and by centrifugal action be directed to theedge of the same, and conse-` quently be restored to the interior of thebox above the partition I, llowing thence through an opening in the ribq, and past the frame J into the chamber L.

Fourtlily. The annular flange H on 'thehub of the car-wheel,`overhanging the iiange E of the box, owing to the speed with which itrevolves, repclsl the dust and sand which would otherwise gain access tothe interior of the box.

Although we have illustrated and described the annular flanges G and Has forming a part of the-hub of the car-Wheel, it will be evident thatthey may be separate from the same-and secured to the axle.

We claim as our invention, and desire to secure by Letters Patentl. Theoiling-roller K, framed, and weighted lever M or its equivalent, thewhole being constructed and arranged within a journalbox, and operatingsubstantially as and for the purpose herein set forth. A

2. Thepartition I, oilharnber L, frame J, and oiling-roller K, the wholebeing arranged substantially as set forth,for the purpose speci- O.BEECHER. R. E. ROGERS.
